​This batch mode edition is unusually long. It covers the past month and a bit more. Yes, that's way too much and I won't try to repeat the experience ;-) Here's what I considered pertinent enough to share with you. Exceptionally, in some cases I haven't gave attribution to the source of the news, thank you for your comprehension.

LightSquared 4G Plans Interfering with GPS Prevented by New U.S. Defense Act?

Via @azolnai I learned about the 2012 Defense Authorization act that may prevent LightSquared, or anyone else, to interfere in any way with military GPS. Related, last week, Slashdot discussed a story named LightSquared Says GPS Tests Were Rigged.

From the NewScientist article: "A clause buried deep in the 565 pages of the 2012 Defense Authorization act passed in December bars the Federal Communications Commission from approving systems that interfere in any way with military GPS. The bill also tells the FCC to supply Congress with a final copy of the report from its working group, which late last year issued a preliminary report warning that a system proposed by telecoms firm LightSquared of Reston, Virginia would cause serious interference. [...] The concern was that signals near the 4G transmitters would be so strong that that would drown out the faint satnav signals reaching the ground. A series of subsequent tests backed up those claims."

The Slashdot story summary: "Would-be cellular carrier LightSquared claims that the company's LTE network was set up to fail in GPS interference tests. 'Makers of GPS (Global Positioning System) equipment put old and incomplete GPS receivers in the test so the results would show interference, under the cover of non-disclosure agreements that prevented the public and third parties from analyzing the process,' LightSquared executives said on a conference call with reporters Wednesday morning."

While we mentioned frequently the LightSquared debacle, those interested in all the details can read All Points Blog's excellent coverage.

U.S. Supreme Court Rules Warrants Needed for GPS Monitoring

If you're not sick of it already, Slashdot runs another story on GPS monitoring and the law, this time, it's named Supreme Court Rules Warrants Needed for GPS Monitoring.

Their summary: "The Supreme Court has issued its ruling in the case of Washington, D.C. nightclub owner Antoine Jones, saying police must get a search warrant before using GPS technology to track criminal suspects. A federal appeals court in Washington overturned his drug conspiracy conviction because police did not have a warrant when they installed a GPS device on his vehicle and then tracked his movements for a month."

Microsoft Patents Bad Neighborhood Detection via GPS for Pedestrians

Or for geospatial purists, via 'satellite navigation systems' for pedestrian. In any case, Slashdot discusses a story named Microsoft Patents Bad Neighborhood Detection.

Their summary: "With the grant of their US Patent #8090532 Microsoft may be attempting to corner the market on GPS systems for use by pedestrians, or they may have opened a fertile ground for discrimination lawsuits. ... Described as a patent on pedestrian route production, the patent describes a two-way system of building navigation devices targeted at people who are not in vehicles, but still require the use of such a device to most efficiently route to their destination. ... For example, the user inputs their destination and any constraints or requirements they might have, such as a wheelchair accessible route, types of terrain they are willing to cross, the option of public transportation, and a way point such as the nearest Starbucks on the route. Any previously configured preferences are also considered, such as avoiding neighborhoods that exceed a certain threshold of violent crime statistics (hence the description of this as the 'avoid bad neighborhoods' patent), fastest route, most scenic, etc."

Sat-Nav Problem Summit

A local transport summit is being organized in the UK to look at better and more frequent ways to update the information used by Sat-Nav units (http://www.bbc.co.uk/news/uk-16434183). This is to try to avoid those commonly occurring stories that appear in the media such as large vehicles being sent through narrow streets (http://www.bbc.co.uk/news/uk-15395200) or sent along inappropriate roads (http://www.dailymail.co.uk/news/article-1315762/White-van-man-airlifted-safety-satnav-sends-mountain.html).

U.S. Judge Doesn't Care About Supreme Court GPS Case

First, happy 2012 to everyone! :-)

Slashdot is running a discussion named Judge Doesn't Care About Supreme Court GPS Case.

Their summary: "The Supreme Court is currently deciding whether or not law enforcement needs a warrant before they put a GPS tracker on a person's car. A judge in St. Louis doesn't seem to care about that, though. He ruled last week (PDF) that the FBI didn't need a warrant to track the car of a state employee they suspected was collecting a paycheck without actually going to work. (Their suspicions were confirmed.) While in favor of corrupt government employees being caught, it's a bit disturbing that a federal judge would decide a warrant wasn't needed while the Supreme Court has said the issue is unclear."

China Begins Using New Global Positioning Satellites

Slashdot discussed this story named China Begins Using New Global Positioning Satellites.

Their summary: "cswilly writes with the news that China's satellite navigation system, called Beidou, has been successfully activated. "With ten satellites now, 16 in 2012, and 35 in 2020, China is making damn sure they are independent of the U.S. military's lock on GPS. According to the article, 'Beidou, or 'Big Dipper,' would cover most parts of the Asia Pacific by next year and then the world by 2020.'" The BBC also has slightly more detailed coverage"

We started talking about Beidou in 2006, sometimes under the Compass name.

US Sentinel Drone Fooled Into Landing With GPS Spoofing

Slashdot discusses a story named US Sentinel Drone Fooled Into Landing With GPS Spoofing.

Their summary: "Following up on the earlier Slashdot story, the Christian Science Monitor now reports that GPS spoofing was used to get the RQ-170 Sentinel Drone to land in Iran. According to an Iranian engineer quoted in the article, 'By putting noise [jamming] on the communications, you force the bird into autopilot. This is where the bird loses its brain.' Apparently, once it loses its brain, the bird relies on GPS signals to get home. By spoofing GPS, Iranian Engineers were able to get the drone to 'land on its own where we wanted it to, without having to crack the remote-control signals and communications.'"

LightSquared Disrupts 75% of GPS Connections In Government Test

Remember this story last February named LightSquared and FCC: How GPS Signal in the U.S. May Soon No Longer Operate Correctly? Well, Slashdot is now running a discussion named LightSquared Disrupts 75% of GPS Connections In Government Test.

Their summary: "Philip Falcone's proposed LightSquared Inc. wireless service caused interference to 75 percent of global-positioning system receivers examined in a U.S. government test, according to a draft summary of results. ... The tests worked off an 'extraordinarily conservative' threshold and didn't show the devices' performance was affected, [LightSquared exec Martin Harriman said]. 'If we're affecting the performance of the device — my goodness, we'd like to be sure that doesn't happen,' Harriman said. The laboratory testing was performed for the National Space-Based Positioning, Navigation, and Timing Systems Engineering Forum, an executive branch body that helps advise policy makers on issues around GPS. It found that 69 of 92, or 75 percent, of receivers tested 'experienced harmful interference' at the equivalent of 100 meters (109 yards) from a LightSquared base station."

We mentioned the LightSquared debacle a few times in the past.
